Virgin Mary Miraculous Medal Seton Hill

Lovely large old medal for Virgin Mary, the Miraculous Medal, this one unusual, surrounding the Virgin is "Monstra Te Esse Matrem" which is latin for Show thyself to be a Mother, as found in the latin lyrics for the Ave Maria Stella. On the back the Miraculous symbols with particularly nice Sacred and Immaculate Hearts and a crest that must have something to do with Seton Hill. This is a large medal, heavy for the size,measuring 1 & 3/8" including the bale but not the extra loop, and it is in good condition with some age wear from being loved. It is of a silver tone metal, heavy and fine quality that resembles sterling but we can not find any markings as such.
